Answer:

Step-by-step explanation:

4x + 3y + x + 4y

= 4x + x + 3y + 4y

= 5x + 7y

4x + 3y + 2x - y

= 4x + 2x + 3y - y

= 6x + 2y

4x + 5y - ( x + 4y )

= 4x + 5y - x - 4y

= 4x - x + 5y - 4y

= 3x + y

2x - y + 3x + y

= 2x + 3x - y + y

= 5x + 0

= 5x

A cone has a height 25 ft and a radius of 7 ft. Is a reasonable that the volume of this cone is 100 ft3? Why or why not?​
Nostrana [21]

Answer:

No

Step-by-step explanation:

the radius squared is 49 times π, which is roughly 3 means the area of the base is roughly 150 ft².

This means that one third of the height cannot be more than 100 / 150 = 2/3 of a foot. That makes the height about 2 ft, much less than the reported 25 ft.

Given line AB and point O on that line, any ray that can be drawn with its endpoint at O can be put into a one- to-one correspon
natima [27]

Answer:

Protractor

Step-by-step explanation:

A POSTULATE, LAW OR THEORY SHOULD NEVER BE ALTERED

∴ The protractor postulate states that the measurement of an angle between two rays can be designated as a unique number, and this number would be between 0 and 180 degrees, Hence for every angle A, there corresponds a positive real number less than or equal to 180. This postulate guarantee the use of a protractor to measure angles.

Hence, Given line AB and point O on that line in such a way that any ray that can be drawn with its endpoint at O can be put into a one- to-one correspondence with the real numbers between 0 and 180 is a statement that explains Protractor's Postulate.

How do I solve #14????
Tcecarenko [31]
All the measures in a triangle are equal to 180 degrees.

Let the unknown angle= x.

40+89+x= 180

Combine like terms.

129+x= 180

Subtract 129 from both sides.

x= 51

The angle is equal to 51.

I hope this helps!
